اسطوانة الإعجاز العلمي في القرآن والسنة – الشيخ عبد المجيد الزنداني

No comments:

يقول المحدث الفقيه أبو إسحاق: وأنت في مرحلة المقاومة استعد للبلاء ! سيرمونك عن قوس واحدة ! لكن من ثمرة هذه المرحلة المباركة ! أنك تخرج منها قوي القلب ! فإن القلب لايقوى إلاّ في مرحلة المقاومة !!

ويقول: إن هذا الدين لا يباع وإنها ساعة بعدها يحط المسلم رحله في الجنة وينسى بؤسه قط بعد غمسة واحدة فيها.

جزاك الله الجنه و سقاك من انهارها... فكر وتدبر لتكون صاحب قرارك لا سجين غرورك

اللهم اغفر لى ذنوبى اللهم استر عيوبى اللهم انى اسألك الهدى و التقى و العفاف و الغنى اللهم اغنى جميع المسلمين من فضلك الذى لا ينفد

روى مسلم وأحمد وابن ماجه وغيرهم من حديث نافع بن عتبة أن النبي صلى الله عليه وسلم قال: (تغزون جزيرة العرب فيفتحها الله، ثم تغزون فارس فيفتحها الله، ثم تغزون الروم فيفتحها الله، ثم تغزون الدجال فيفتحه الله).

اللهم آمين

¶	window.onload = function() { var element = document.getElementById('container') dropAndLoad(element, init, "ArrayBuffer") }
¶ Reusable dropAndLoad function: it reads a local file dropped on a `dropElement` in the DOM in the specified `readFormat` (In this case, we want an arrayBuffer)	function dropAndLoad(dropElement, callback, readFormat) { var readFormat = readFormat \|\| "DataUrl" dropElement.addEventListener('dragover', function(e) { e.stopPropagation() e.preventDefault() e.dataTransfer.dropEffect = 'copy' }, false) dropElement.addEventListener('drop', function(e) { e.stopPropagation() e.preventDefault() loadFile(e.dataTransfer.files[0]) }, false) function loadFile(files) { var file = files var reader = new FileReader() reader.onload = function(e) { callback(e.target.result) } reader['readAs'+readFormat](file) } }
¶ Once the file is loaded, we start getting our hands dirty.	function init(arrayBuffer) { document.getElementById('instructions').innerHTML = 'Loading ...'
¶ Create a new `audioContext` and its `analyser`	window.audioCtx = new webkitAudioContext() window.analyser = audioCtx.createAnalyser()
¶ If a sound is still playing, stop it.	if (window.source) source.noteOff(0)
¶ Decode the data in our array into an audio buffer	audioCtx.decodeAudioData(arrayBuffer, function(buffer) {
¶ Use the audio buffer with as our audio source	window.source = audioCtx.createBufferSource() source.buffer = buffer
¶ Connect to the analyser ...	source.connect(analyser)
¶ and back to the destination, to play the sound after the analysis.	analyser.connect(audioCtx.destination)
¶ Start playing the buffer.	source.noteOn(0)
¶ Initialize a visualizer object	var viz = new simpleViz()
¶ Finally, initialize the visualizer.	new visualizer(viz['update'], analyser) document.getElementById('instructions').innerHTML = '' }) }
¶ The visualizer object. Calls the `visualization` function every time a new frame is available. Is passed an `analyser` (audioContext analyser).	function visualizer(visualization, analyser) { var self = this this.visualization = visualization var last = Date.now() var loop = function() { var dt = Date.now() - last
¶ we get the current byteFreq data from our analyser	var byteFreq = new Uint8Array(analyser.frequencyBinCount) analyser.getByteFrequencyData(byteFreq) last = Date.now()
¶ We might want to use a delta time (`dt`) too for our visualization.	self.visualization(byteFreq, dt) webkitRequestAnimationFrame(loop) } webkitRequestAnimationFrame(loop) }
¶ A simple visualization. Its update function illustrates how to use the byte frequency data from an audioContext analyser.	function simpleViz(canvas) { var self = this this.canvas = document.getElementById('canvas') this.ctx = this.canvas.getContext("2d") this.copyCtx = document.getElementById('canvas-copy').getContext("2d") this.ctx.fillStyle = '#fff' this.barWidth = 10 this.barGap = 4
¶ We get the total number of bars to display	this.bars = Math.floor(this.canvas.width / (this.barWidth + this.barGap))
¶ This function is launched for each frame, together with the byte frequency data.	this.update = function(byteFreq) { self.ctx.clearRect(0, 0, self.canvas.width, self.canvas.height)
¶ We take an element from the byteFreq array for each of the bars. Let's pretend our byteFreq contains 20 elements, and we have five bars...	var step = Math.floor(byteFreq.length / self.bars)
¶ `\|\|\|\|\|\|\|\|\|\|\|\|\|\|\|\|\|\|\|\|` elements `\| \| \| \| \|` elements we'll use for our bars	for (var i = 0; i < self.bars; i ++) {
¶ Draw each bar	var barHeight = byteFreq[istep] self.ctx.fillRect( i (self.barWidth + self.barGap), self.canvas.height - barHeight, self.barWidth, barHeight) self.copyCtx.clearRect(0, 0, self.canvas.width, self.canvas.height) self.copyCtx.drawImage(self.canvas, 0, 0) } } }
